Non-Local Object Information Utilization: From Ghost Imaging to Orbital Angular Momentum Correlation

This article delves into the realm of non-local methods for utilizing object information, drawing a compelling parallel between the established technique of ghost imaging and a novel method leveraging the correlation properties of entangled photons in the dimension of orbital angular momentum.

We introduce ghost imaging in the introductory section to highlight the shared principle of non-local object information utilization. While ghost imaging exploits the correlation of entangled photons in the position or momentum dimension, our method focuses on their correlation in the orbital angular momentum dimension.

The essence of both approaches lies in their ability to achieve non-local measurement by facilitating information exchange between the object and the entangled photons. This intriguing parallel underscores the versatility of entangled photons in enabling non-conventional measurement strategies.

To ensure clarity and coherence, we have enriched the article with detailed descriptions, elucidating the principles and nuances of both ghost imaging and our proposed method. This comprehensive approach allows readers to grasp the intricacies of non-local object information utilization and appreciate the novelty of our proposed technique.
